Billionaire businessman Jared Isaacman has a big vision for humanity's future.
In 2021, he embarked on his first space mission, a private journey he funded for an estimated $200 million (£160 million). He announced his desire for space travel to be accessible to everyone, not just the 600 people who have experienced it so far, most of whom are professional astronauts working for NASA or wealthy individuals.
"We want it to be 600,000," he told reporters.
He later added, "I believe in the grand ambitions of humans becoming a multi-planet species. I think we all want to live in a Star Wars or Star Trek world where people are traveling in their spacecraft."
Mr. Isaacman, who earned much of his $1.9 billion (£1.46 billion) fortune from a payment processing company he founded in 1999 at age 16, reportedly funded the rest of the four-person crew aboard the SpaceX craft in the 2021 mission, driven by his long-standing love of flying and fascination with space.
Since then, there have been more adventures. Last year, he showed Captain Kirk-like daring by traveling in an upgraded SpaceX capsule and performing the first commercial spacewalk.
During the mission, he tested an experimental spacesuit and a new cost-saving method to exit and re-enter the spacecraft without using an airlock.
The photograph of Mr. Isaacman, silhouetted with the world at his feet, has become iconic. It showed that he wasn't just a playboy billionaire pretending to be in Star Trek, but someone pushing the limits of what current technology can do.
Yet, a more recent achievement has gained even more attention: being nominated by Donald Trump in December to be the new head of NASA.
